I'm building a new PC and was wondering if I can take the harddrive out of my old PC and put it in my new pc and still be able to use windows 7. Can I do this?

That is a definite 'maybe'

2 issues:
1. Does it boot? Sometimes yes, sometimes no.
2. Licensing. Is that Windows license tied to that original motherboard?

Solution?
Sell the old hardware and buy a new copy of Windows for the new PC.

So you've never heard of anyone trying that and it doesn't work?
You don't read in here enough.

The Windows 7 installation was done on the first motherboard. Does this mean that the OS is tied to the fist on and will not work with the new one?

It depends on the specific license. If it is an OEM license, it is indeed licensed to that original motherboard.
Once it sees new hardware (the new PC), it will deactivate. You can probably get it reactivated by going through Microsoft, but that is not guaranteed. It is entirely up to them whether to allow that.

How to check?
Open Win Explorer, right click on the C drive and select Properties.
At the bottom of the dialog box that open is the Product ID. If it says "OEM" in the middle...thats what it is.

NOTE: that Product IS is NOT the activation key.

As said - moving a drive with an existing Windows install sometimes works, sometimes doesn't.
Saying "Yes you will be fine. " is incorrect, because it does NOT always work well.

As far as your posts being deleted...if you recommend illegal pathways to do this, yes, they will be deleted. Or worse.

What are the chances of it being an OEM install, the computer is running windows 7 home premium 64 bit. Would it say it on the box?

All depends on where it came from and how it was installed.
Was this a preinstalled OS?

Still, depends on what license it was that you bought.
However...if this was originally a Vista PC, that drive is now pretty old. I wouldn't use it for the primary drive n a new PC. IMHO, anyway.

Am trying to do the same thing. With the current build I bought a new copy of MS Windows 7Professional when I put the system together myself. I am going to buy a second License for MS Windows 7 Professional for the 2nd system.
or , according to this web site:http://lifehacker.com/5958507/uninstall-your-windows-pr..., you can use your old license on another computer if you uninstall the license on the old computer. OTW check with Microsoft Retail licences allow activation on different hardware (1 at a time). Hope this covers legalities.

There are ways to clone your current HD and move it to a new system. If you have 2 systems you need a licensed copy of Windows for each. You can reactivate Windows 7 on the 2nd system with the new copy of Windows 7. Keep it legal.
Several things to remember;
if the original OS came with your current PC, it will not work. OEM systems are stuck with the mobo they were originally installed. If, however, you have a genuine MS version of the OS, it might work. If you junk your old system, then transferring the op sys might be ok.
I recommend backing up your old hard drive first

When you swap the HD into new hardware and start up, it will switch (probably) out all of the drivers requesting several restarts. I have experienced no big problems doing this. Some say it will not work on a different number of cores, but I haven't tried it yet.
you will need to make a backup boot copy while you are currently running windows.

I always immediately go to Computer>Properties and reinstall the product key (only if I am not going to keep the 1st computer) otherwise install your NEW key for the NEW computer.

Others have said that isn't necessary. Assume it requires reactivation on new hardware.
If activation fails, you can always run a Repair Install which resets activation.

You have to make a bootable CD
You have to format/activate the new drive on your system before you do all this.
There is a myriad of cloning software mentoned in forums on the net for this topic.

Yes it can be done, legally.
